“…The lesions of HU consisted of typical erythematous and oedematous weals, varying in size from a few millimetres to a few centimetres, strictly confined to the area of heat contact, with the exception of giant hives in IG‐HU . Itch was present in almost all cases in all subtypes of HU with mild to moderate intensity; it was severe in approximately 18% of patients with IL‐HU and 27% of patients with IG‐HU . In a few cases, lesions were indurated or swollen and sensitive to touch, but not pruritic.…”

“…Warm baths represented the most common trigger, occurring in 85% of cases of HU. Hot air (generated from hot radiators, open fire, heating pads, oven steam, heated stove, hair dryers, lasers or intense pulse light or electrocautery, sunlight either direct or glass‐filtered or after cooking or sitting in a hot car) was the second most frequent heating stimulus, reported by 52% of cases of HU. Exposure to sun induced lesions in half of the patients of all subtypes of HU.…”

“…Moreover, in 44% of cases of HU cutaneous lesions were induced from contact with warm objects (such as plates or coffee mugs, clothes, blankets and hot water bottles). Swelling, pruritus or irritation of the palate or lips could be induced by hot foods and drinks in about one‐third of patients with immediate‐onset HU, but never in the delayed type . Weals occurred at any skin area exposed to the heating stimulus.…”

Heat urticaria (HU) is a rare type of physical inducible urticaria, characterized by itchy erythema and well-demarcated weals appearing soon after heat exposure. Most cases occur in female patients aged 20-45 years. Both localized and generalized forms exist, depending on the limitation of the reaction to the skin area directly exposed to the physical stimulus or the involvement of distant sites, respectively. In most cases, HU is an immediate reaction, but delayed forms (mostly familial) have been described. HU is a long-lasting disease with overall duration at diagnosis of approximately 2 years. In about half of cases it is associated with systemic symptoms such as weakness, wheezing, headache, flushing, nausea, vomiting, diarrhoea, tachycardia, even dyspnoea or syncope. The main differential diagnosis includes cholinergic urticaria, exercise-induced anaphylaxis and solar urticaria. The diagnosis of HU is established by provocation testing, which is also helpful to evaluate the critical temperature threshold. The mean threshold temperature is about 44 °C. A heat desensitization programme can be an effective treatment. Nonsedating H1 antihistamines administered at licensed doses are the mainstay of symptomatic therapy in nearly 60% of patients, but full symptom relief is achieved in only a minority of them. Omalizumab has proven effective in recent case reports.
